Abstract: 744,186. Electromagnetic switches. PARVEX. June 17, 1953 [July 28, 1952], No. 16700/53. Class 38(5) A switch intended for starting a single phase motor has its operating winding 3 connected in series with the main motor winding whereby the heavy current flow upon switching on of the motor causes downward movement of a plunger core 4 against the action of a spring 10 to close the motor starting winding through contacts 7, 8. The contacts 7, 8, Figs. 2, 4, are carried by a conducting strip 9 secured, cross-wise, to a blade spring 6 stressed between the resilient arms of a strap 5 attached to the plunger 4. When the core is attracted, the strip 9 engages abutments 16, 17 of the insulated switch casing 1 and forces the blade 6 overcentre so that it is upwardiy bowed and the contacts 7, 8, bridge fixed contacts 12, 13. When the current decreases after the motor has started, the spring 10 moves the strap 5 upwards and the spring 6 is reversed to its initial position due to the reaction between the contacts 7, 8, 12, 13, which then separate. A screw 11 permits adjustment of the operating-current value. The abutments 16, 17 may comprise auxiliary contact studs. In a modification. Fig. 8, a pair of blades 22, 23 act between the strap 5 and a contact-carrying cross-piece 24 of inverted channel section.

Abstract: 899,573. Automatic control systems for aircraft. SPERRY GYROSCOPE CO. Ltd. May 22, 1959 [May 23, 1958], No. 16744/58. Class 38 (4). Servomotor-operated elevators of an aircraft are automatically controlled by an electrical signal formed by a particular algebraic combination of components dependent on deviation of airspeed from a desired value, rate of change of airspeed, and rate of change of pitch attitude of the aircraft. As shown, an airspeed responsive differential bellows 4 associated with static and dynamic pressure heads through conduits 2 and 3, operates a potentiometer P1 connected in a D.C. bridge circuit, the output of which, representing deviation of speed from a value set by a spring-loading knob 15, is applied through an amplifier 17 to control a servo 18 adjusting elevators 19 to correct the deviation. Follow-up signals from a potentiometer P3 adjusted with the elevators are applied to the input of amplifier 17. A signal from a potentiometer P2 adjusted by a rate of pitch gyro 16 is applied to amplifier 17 through a resistancecapacity network 20 which develops an additional control component representative of rate of change of speed. Adding a low-pass filter or an integrator to the speed error signal circuit is referred to. Automatic throttle control may be introduced additionally if airspeed falls below a predetermined value.

Title: Fluid transfer valve structure
Inventor: COULTER WALLACE HENRY
IPC: B01L99/00
Filed: 1969-03-31
Abstract: 1,268,937. Proportioning mixture components; sampling valve. COULTER ELECTRONICS Ltd. 31 March, 1969 [3 April, 1968], No. 16811/69. Headings B1C and B1X. [Also in Divisions B8 and F2] Apparatus for separating and diluting a measured sample of liquid comprises a valve 10, having two fixed sections 12, 16 each with four ports P1-P4 and P5-P8 respectively and a central rotatable section 14 with two passages P9; P10 which can alternately connect two pairs of diagonally opposite ports, the three sections 12, 14, 16 being biassed together, but the biassing being partially relieved during rotation of the section 14. Operation. When the passage P9 is aligned with ports P1, P5, as shown in Fig. 2, liquid to be sampled is drawn from a vessel 36 through a three-way valve 22 by a pistonoperated pump 56 so that the passage P9 contains a sample. The section 14 is then rotated to align the passage P9 with ports P2, P6 and a further three-way valve 26 is operated to dispense a measured volume of the diluting liquid, pumped by one stroke of a further piston operated pump 62 from a vessel 72 into a line 24 and along with the sample in the passage P9, into the container 44, from which part of the sample may be run off and tested. The diluted sample in the container 44 may be further diluted by a similar process, that is, raising the diluted sample into the passage P10, now aligned with ports P4, P8, by the pump 56 and three-way valve 22, then rotating the section 14 to align the passage P10 with ports P3, P7 so that the volume of diluted sample contained in the passage P10 may be further diluted with a measured volume of diluting liquid and transferred to a container 50 for testing. Construction. The three valve sections 12, 14, 16 are held on a spindle 300, rotatably mounted on a plate 302, by a bolt 312. The spindle 300 is rotated by an arm 326, connected by a universal joint 329 to a piston reciprocating at right angles to the plane of Fig. 6, thus causing the section 14 to rotate, as this section has a rectangular axial hole corresponding to a rectangular sectioned portion 304 of the spindle 300. A rod 306 engages with grooves 310 in the sections 12, 16 preventing their rotation and with shoulders 314 on the section 14 to limit its rotation. The bolt 312 screws into a piston 334 which is biassed away from the plate 302 both by a spring 338 and by a diaphragm 356 acted on by compressed air introduced through an inlet 358 and abutting a plate 348 fixed to the piston. This biassing prevents leakage between the sections 12, 14, 16 when stationary; however, when it is required to move the section 14, a servo mechanism (not shown) relieves the compressed air acting on the diaphragm so that only the spring 338 biasses the sections together thus reducing the wear. Movement of the piston 334 is limited by a pin 344 moving within a groove 343.
